Subject: Re: [Contiki-developers] Further Discussion About A Port to TI
CC430(MSP430 SoC with CC1101 RF Core)
The thread [cc1101 in Contiki] is not a thread but a private message. But,
anyway: the nesC code is provided by Sownet which sells a node with that
radio (CC1101). A translation of this code shouldn't be difficult but it
would help a lot understanding a bit more the Contiki stack and knowing
which functions does it expect from a radio driver. Is there documentation
on this?
However as an intermediate step I set out to port the simple blink
application to prove that the whole toolchain works and even this isn't that
easy. My platform has a MSP430F2418 and the code under the cpu/ folder isn't
generic for the whole MSP430 family. So you get erros in registers'names for
SPI, UART, etc.
I think the big question is if the Contiki core developers want to make it
easy to port or not. I mean, everyone knows this is not an easy issue, but
welcome to the embedded world and its thousands of hardware configurations!
Have a nice day,
Gonçalo

I must point out that the NanoStack 2.0 specifically supports CC430, not
just "potentially support" as I mentioned before.

Hey guys,
In a previous thread [Any Contiki Port to TI CC430(MSP430 SoC with CC1101 RF
Core)?] at
http://sourceforge.net/mailarchive/message.php?msg_id=28731679
(1) Gonçalo and Ansays mentioned that they are working on porting Contiki to
two different motes both with CC1101 independently;
(2) Maciek says that "You can port Contiki to that, but it won't be
compatible with other devices (ravens, econotags, etc.)";
(3) Jon says that "......, it just means that it(CC1101, commented by Sean)
probably can't talk to standard 802.15.4 radios. It is likely that it can't
generate ACKs with the proper timing."
Since some people here either have the similar interest as me or have
already done some related work, I dug a little bit on the web and found two
pieces of information that might be interesting to some of you. Moreover,
I'd like to know more people interested or working on such a port so that we
might be able to progress faster.
I found one proprietary binary library which potentially supports CC430 and
it's also listed on TI's CC430 official web page. It's Nanostack at
http://www.sensinode.com/EN/products/software.html
And the other is OSIAN(
http://en.wikipedia.org/wiki/OSIAN), which is
probably well-known to the TinyOS community. The OSIAN stack was designed
primarily for CC430 and it was claimed to be open source. However, I don't
see any recent updates in the code repository and I also couldn't open its
official website(
http://www.openosian.net/). Plus, the development
platform(SuRF Developers Kit,
http://www.wired.com/gadgetlab/2010/05/people-power-gadgets/) previously
offered by People Power(
http://www.peoplepowerco.com), which developed
OSIAN, doesn't seem available any more.
According to these information, I guess point (3) above can be answered. I
still don't understand what Maciek pointed out in (2). Why such a port won't
be compatible? And I read another thread [cc1101 in Contiki] posted by
Gonçalo which attached a CC1101 driver written in nesC, I'm wondering which
project it belongs to and how it is going with getting it working?
Please join us and discuss more about a Contiki port to CC430.
Regards,
Sean
